<p>PROBLEM TO BE SOLVED: To provide an elevator capable of reducing rope vibrations due to long-period vibrations of a building.SOLUTION: An elevator device includes: an acceleration sensor 31 which detects long-period vibrations of a building; a rope vibration waveform estimation part 33 which generates a vibration waveform of a rope on a floor where a car is at a stop based upon the detected long-period vibration waveform of the building; a rope hitch driving control part 34 which generates a waveform signal opposite in phase to the vibration waveform of the rope; and rope hitch driving devices M1, M2 which vibrate a rope hitch device 20 for connecting the rope to the car with an output signal of the rope hitch driving control part 34.</p> |
